The rule is that the trader relinquishes one coconut from each sack at each checkpoint. Such a strange toll. And the trader starts with 90 coconuts, or 30 per sack.
The journey begins…
Being intelligent (or clever ), the trader realizes the loophole in the said rule and moves all coconuts and sacks into one sack. The trader pays exactly one coconut at each of the 30 checkpoints, leaving the trader with a big sack of 60 coconuts plus two empty sacks.
Too easy? Alright, let’s assume that the maximum capacity of each sack is 30 coconuts. The trader passes through 10 checkpoints, leaving the trader with 20 coconuts per sack. At this point, the trader distributes all coconuts from one sack into the other two sacks, leaving two sacks each filled with 30 coconuts. The trader also sells the third sack at a nearby marketplace. I assume that the local currency is in something other than coconuts, which may be a dangerous assumption.
After passing through 15 more checkpoints, the trader now has 15 coconuts per sack, or 30 coconuts in total. Transfer the coconuts into one sack, sell the other sack, rinse and repeat. Now, the trader is left with 30 coconuts in a sack. Pass through the five remaining checkpoints and the trader is left with 25 coconuts plus one sack plus whatever was made selling the other two sacks.
